<p>I don't think this has ever been discussed. Both are going all out. Itachi is in his prime but Gaara is not.
</p><p>Knowledge: not much for gaara, manga for itachi
</p><p>Location: A Desert

<p>You just gave Gaara the desert, he automatically gets so much more options to win with that. Itachi may be able to win 6 out of 10 battles, but in Gaaras case with the desert I give Gaara 6 out of 10 battles.
